I have 6 bantams, OE, Dorkings and silkies. They free range all day long in a 34' x 32' area. they love it when I bring them tomatoes, zucchini, corn, cucumbers, etc. my husband was worried that on of them may have worms because she is smaller than her sister (dorking hens). plus the poo can sometimes be runny, like diarreah. it is not always like to however, so I was wondering if the type of food they eat can effect their poo??
